Systems for mixing and dispensing single and multiple component fluid materials are known in the art. In the case of multiple component materials, the systems may include mechanisms for pumping the components to a mixing device that thoroughly mixes the components together. The mixed composition then flows out the mixing device for use. For example, the components may be reactive materials that require stirring or mixing for a reaction to take place, e.g., multi-part epoxies, silicones, polyesters, urethanes and acrylics, or non-reactive components that are mixed or stirred together, e.g., components of different colors which are mixed together to provide a composite color, liquids and solids, powders.
Dynamic mixing devices known in the art have generally been relatively expensive devices. The devices can be relatively difficult to clean after use, and thus are relatively expensive to maintain as well.
